How to limit default xmlnamespaces?

Question

I have the following Tsql script:
; with xmlnamespaces (
default 'http://www.tn.gov/mental/Schemas/CrisisAssessment', 'http://www.w3.org/2001/XMLSchema-instance' as xsi)
, prov as (
select NPI,FileCreationDate,
cast(FileCreationTime as time) FileCreationTime
from [August_Import_Data_Final]
group by NPI,FileCreationDate, FileCreationTime
SELECT
NPI as [NPI],
FileCreationDate as [FileCreationDate],
cast(FileCreationTime as time) FileCreationTime,
Select
ProviderPatientNo ,
Select
t_phone.ProviderPhoneAssessmentId,
t_assess.ProviderF2FAssessmentId as [F2FAssessment/ProviderF2FAssessmentId],
AssessmentDate as [F2FAssessment/AssessmentDate],
case when [DateTransportedToFacility] is null then 'true' else null end as [F2FAssessment/DateTransportedToFacility/@xsi:nil], 
[DateTransportedToFacility] as [F2FAssessment/DateTransportedToFacility/*]
FROM (select distinct ProviderPatientNo, ProviderPhoneAssessmentId,ProviderF2FAssessmentId,CallEndDate,CallEndTime,DispatchDate,DispatchTime,
CallDisposition,DispositionOther,Notes
from #phones where CallDisposition in (1,5,8) and ProviderPhoneAssessmentId = t_base.ProviderPhoneAssessmentId) t_phone
inner join #Assessments t_assess On t_phone.ProviderPatientNo = t_assess.ProviderPatientNo and t_assess.ProviderF2FAssessmentId is not null
left join #Drugs d on d.ProviderF2FAssessmentId = t_assess.ProviderF2FAssessmentId
left join #HospAlt ha on ha.ProviderF2FAssessmentId = t_assess.ProviderF2FAssessmentId
left join #HospDisp hd on hd.ProviderF2FAssessmentId = t_assess.ProviderF2FAssessmentId
FOR XML PATH('PhoneAssessment'), ELEMENTS, type) AS [*]
FROM (select distinct ProviderPhoneAssessmentId, ProviderPatientNo,LastName,FirstName,SSN,DOB,Gender,Race,Ethnicity from #base
) t_base
FOR XML PATH('Patient'), type
from prov
for xml path(''), root('Provider')
But this results in output like:
<Provider xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.tn.gov/mental/Schemas/CrisisAssessment">
<NPI>1306875695</NPI>
<FileCreationDate>2014-02-05</FileCreationDate>
<FileCreationTime>09:24:25</FileCreationTime>
<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.tn.gov/mental/Schemas/CrisisAssessment">
<ProviderPatientNo>146477</ProviderPatientNo>
(Don't worry about the details in my first Tsql query; just focus on the xsi element only).  Instead of the above XML, I want it to look like:
<Provider xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.tn.gov/mental/Schemas/CrisisAssessment">
<NPI>1306875695</NPI>
<FileCreationDate>2014-02-05</FileCreationDate>
<FileCreationTime>09:24:25</FileCreationTime>
<Patient>
<ProviderPatientNo>146477</ProviderPatientNo>
So I only want this xsi attribute to appear one time at the beginning of my file.  How can I do this?  And make all of the Patient tags appear as just <Patient> instead?

I don't think that there is a way to do that easily.
